Letters Patent No. 90,937, dated June 8, 1869m`- IMPROVED HANG-ER FOR SHAFTING.

The Schedule referred to in these Letters Patent and making part of the same.

Be it known that I, JAMES DUFF, of the city of Peoria, inthe county of Peoria, and State of Illinois, have invented a new and useful Improvement in Oiling-Boxes; and I do hereby declare that the following isa full, clear, and exact description of the constructionA and operation of the' same, reference being had to the annexed drawings', making a part of this specification, in which- Figure l is a perspective view;

Figure 2 is a vertical section;

Figure 3 is a view of the upper side of the'cap of the journal-box, and cover ofthe oil-box;

Figure 4 is an elevation of the lower half of th journal-box; Y

Figure 5 is a longitudinal elevation of the lower half of the j ournal-box; and

Figure 6A is a view of the under side of the lower half of the journal-box.

My invention consists of an oil-box being cast with the bracket, and having therein centre-bearings, so combined with the journal-box, constructed with arib on the bottom, and projections from the sides and ends thereofas that the journal-box may have a rocking motion on the bearings, and thus adjust itself to the shafting, when out of line, the rib preventing the box from revolving with the shaft, and the projections retaining the box properly on the bearings.

My invention also consists, in combination with the above, in constructing an opening in the side of the journal-box, on each side of the projection thereof,

and' also a channel between the same, by which the wick may feed the oil tothe shaft from the side ofthe box, by its being introduced through one opening, and

i then passed along the channel, and thence through the .other opening into the oil-chamber.

I am aware that wicks have been usedA before for feeding oil to the shaft, but they have been used to feed the oil mostly from the bottom of the boX, making it diiicult, therefore, to replace the wick,Y when gummed.

I am also aware that there is one which feeds the oil partly from the side,'but the wick, in this, is confined in a groove, cast in the journal-box, which is so arranged, that the same diiiiculty is experienced, in getting at the wick, as above, to replace it, when gummed.

I am also aware that a 'journal-box is used, hav'- ing a centre-bearing, b'ut it isfused without wicking,

being constructed with perforations, to receive the oil, which fill and choke up, and are, therefore, objectionable.

Now, it will be obvious, by setting the journal-box in the oil-box, on the bearings thereof, an ample space will be left around the sides and ends, for the oil to feed, orflow freely through the wick, and pass into the ends and sides of the section E, by

the box again, and that the wick may be readily got at, for removal, and the supplying of its place with a new one, when gummed. f

I construct my oil-box B lof any convenient form, and of a size proportionate to the size of the journal-box, having an opening, for the admission of the journal, and recesses l l, in which the cap of the journal-box rests, which cap also serves as the cover of the oilbox.

I make centre-,bearings t' 'i in the oil-box, upon which the lower section of the journal-box Erests, and which serves as a pivot, upon which the bearing rocks, and adjusts itself to the shafting, when out of line.

In the bottom of the oil-box B, I make a drip-hole, l

and provide the same with the plugfr.

I makemy journal-box in two sections, the cap O, and lower section E.

The latter is made to fit the lower half of the journal, shorter than the cap, and provided with projection's q q g q, of equal length, extending from the corners and prolonged, so as to make the length of the whole equal to the length of the cap.

In the inner edge of this section, upon one side, I make ya channel, b, extending through the whole length of the box, and also upon the same side, the openings n n, through whichthe wick a passes.

Upon the sides of the lower section E, I make the projections m m 'm m, of such length, and having the ends so formed, as to rest against'the inner side of the oil-box, and attach to the bottom of the section, the rib k, so placed, as to rest between the centre-bearings i i, and prevent the journal-box from revolving with the shaft.

This arrangement leaves an open space, both upon means of which the oil is conducted backfrom the journal to the oil-box.

I make the cap O with or without the oil-oup and dripholes, in common use, fitted to the upper half of the journal, and forming, with the lower section E, a complete journal-box.

From the sides, I extend the lips p p, so as toV cover the open space between the journal-box and oil-box, and fit closely into the recesses Z Z, and bring out the ends of the cap, until they become iiush withlthe ends -of the oil-box.

The apparatus, having been arranged as herein described, and oil and wick supplied, the oil is (raken up from the oil-box, to the side of the journal-box, through the wick a, by capillary attraction, and flows back into the oil-box, over the ends and sides of the bearings.

The wick being at the side of the journal, may be changed, by simply removing the cap.

As none of the oil escapes, it may be Vused until it loses its lubricating-qualities, and, then drawn 01T, by removing the plug fr.

The oil-box may be filled, by simply removing the cap C.

C' laim.

having therein centre-bearings i c', in combination with the journal-box E, provided with the rib k, projections m fm and q q, and wick-openings n n on the side thereof', the whole constructed substantially as herein described and shown.

Y JAMES DUFF.
